fpga驱动单个灯构成的点阵的程序

这是一个基本的ARM7_Core 有基本功能 但不是太完善-This is a basic ARM7_Core has the basic functions, but not too perfect

QFSK的调制与解调，用C写的主程序，汇编写的调制与解调的子程序(QFSK the modulation and demodulation, with the main program in C, compile writing, the modulation and demodulation of the Subprogram)

本代码绝对真实可靠，原用于长沙理工大学EDA课程设计之出租车计费器。本代码在要求的基础上添加显示时速和报警功能。希望此代码对有此需求的同学有所帮助！

键盘输入液晶模块显示字符,在液晶显示屏上显示从PS2键盘输入的字符-Keyboard input LCD display module characters displayed in the LCD screen from the PS2 keyboard input characters

温度控制系统.运用ds18b20温度传感器将实时温度送入FPGA中，再将温度显示出来(Temperature control systems. Use ds18b20 temperature sensor into the FPGA in real-time temperature, then the temperature is displayed)

说明：  基于fpga状态机的交通灯设计，亮灯时间自己修改，程序简单易懂。(Traffic light design based on FPGA state machine, light time self-modifying, the program is simple and easy to understand.)

讲述软解调很不错的一片文档，主要阐述的是8PSK的软解调FPGA实现，但对8PSK的软解调原理阐述很清楚，没有多余的东西，但需要注意其中各个调制符号点得顺序。(About soft demodulation of a document is very good, mainly on the soft 8PSK demodulation FPGA, but soft 8PSK demodulation principle describes very clearly, no extra stuff, but need to pay attention to the point where each modulation symbol was in order.)
